This video is dedicated to CAM and CRK sensor testing and operational parameter, but from an electrical and wiring diagram interpretation point of view. The CAM and CRK sensors are types of speed sensors. There are variations of each and these varieties will dictate the way you test the sensor. Explained here are specific electrical values, such as voltage signals and how the sensor is connected to the ECM itself. This is vital information since most of the diagnostic time is spent in analyzing the wiring diagrams for the component in question.
Presented here using the latest CG and graphic animation technology. Part of our wiring diagram set of videos shown here on this channel. Enjoy...

Explains the Knock Sensor Operation and Testing. The Knock sensor is a actual microphone screwed into the engine block. It is tuned to listen to the exact frequency of an engine knock, which is a high frequency ping. A failing knock sensor will cause all sorts of problems to engine operation, such as skewed timing controls, loss of performance and power and ever the system going to linp-in mode. Learn how it works and how to test this incredible component. (note: We allow all schools and training institutions to use our software free of charge, so long as it is not sold to others.

The CAM sensor or camshaft position sensor's role is to signal the ECM the camshaft position. The crank and cam sensor operate in sync with each other. Without the CAM sensor the vehicle may not even start and cause hard starting. The CAM sensor is mostly used to determine which injector to fire in a sequential system and for COP or coil on-plug ignition systems coil firing event.

Quick Tip-Throttle Cleaning - EricTheCarGuy
This one goes out to BowlingBallOut who posted a question about a sticky throttle on his Saturn. It was a great question so I decided to make this video in response to it. There are many different configurations of throttle assemblies but for the most part if you have a throttle that is sticking you might be able to fix it using the procedures in this video. I am aware you may not able to purchase spray throttle cleaner in some states now but I'm sure they have some alternative available at your local parts store.

Bad Cam Position Sensor?
Takes a bit for my tach to move when starting it. And during idel after starting you can see the rpms bouncing up/down a little bit. These rpms coincide with the vibrations
2003 Nissan Altima S - Camshaft & Crankshaft Position Sensors
2003 Nissan Altima S 2.5L W/Automatic Transmission
PROBLEM:
INTERMITTENT NO-STARTS & ROUGH-STARTS WITH NO DTCs SET.
A LOCAL AUTOSHOP HAD REPLACED ONLY THE CAMSHAFT POSITION SENSOR, MADE SURE NO DTCs PRESENT AND OPS CHECK GOOD.
HOWEVER, THE PROBLEM RETURNED.
NOW, THE SAME AUTOSHOP BELIEVES THAT THE FAULT IS WITH THE TRANSMISSION FLEX PLATE, WHICH MAY HAVE DAMAGED THE CRANKSHAFT POSITION SENSOR AS WELL, ACCORDING TO HIM.
ESTIMATE IS AT ~$750.
The mechanic didn't try to replace the Crankshaft sensor alone, he went straight for the Tranny drop. I figured go with the cheap fix first. If it comes back, then we will look into the Flex Plate.
I replaced the recently replaced Camshaft sensor & the never been replaced Crankshaft sensor. So far, so good.
Replacing the Camshaft sensor is a 2-minute job.
The Crankshaft sensor will likely take 30 times as long.
It seems like the Old Crankshaft Position sensor I removed was a bit high on a resistance check, when compared to brand new sensors. With too high a resistance value, the sensor may not make use of the full voltage it is receiving and/or it may not return the required amount of voltage to the Powertrain Control Module (PCM), which will lead to irregular engine operation or a no-start condition.
Both Camshaft & Crankshaft sensors are the same part number. The 3rd version of the sensor is encased in metal, not plastic.
The OEM part number is 23731-6N21A ($44 us)
The old part numbers were encased in plastic. These part numbers should not be used: 23731-8J005 & 23731-8J006

Nissan recalls that problem to reprogram the ECU. What happens the crank sensor electrical terminals seep oil into the crank sensors plug. The new metal crank sensors correct this problem. Location of this sensor on the back of the motor is difficult to change and you need gorrilia finger grip to depress the connector green lock and remove the sensor. Depending on your cars Vin# Recall Campaign # R0712 NHTSA# 07V-527. Hopefully your factory warranty replaces the sensor no charge 5yr/60,000 mile. The campaign only covers the ECM reprogram. The ECM reprogram makes both sensors act as one so either will allow the car to start. Stalling and not starting is a safety risk.

Common rail injection system
The injection technology used in the TGL and TGM is the most sophisticated one: a state-of-the-art common rail injection system with vertically positioned 7-jet injector nozzle. The latest generation of EDC7 control units provide the controls of the system. Only this system ensures the best-possible control of the fuel injection process. In each compression stroke, the injection quantity can be divided into pre-injection (1) and main injection (2). In some cases, a post-injection (3) is used. The engines operate with an increased maximum injection pressure of more than 1,800 bar in order to reduce the soot particles inside the engine. The engine runs extremely quietly and noise emissions are low due to the pre-injection (1). The common rail system also supplies considerable advantages in torque, particularly at low speeds. At all engine ratings, the favourable progression of torque across a wide range of engine speeds makes driving economical and requires very few gear shifts.
